 Once downloaded, you can fire up a terminal prompt, head to the root directory (i.e. `cd /`) and run `tar -xvzf path-to-thing-you-just-downloaded` to lay out the contents of the tarball onto the filesystem. You can also use the `.pkg` versions if you prefer a clicky-installer wizard, but these installers will remove any previous versions of the framework (kinda defeating the purpose). You can still use the `.pkg` format by heading over to the command line and using `pkgutil --forget` to prevent said clobbering behavior (as noted in [Section 4.2](https://cran.rstudio.org/doc/manuals/R-admin.html#Uninstalling-under-macOS) of _R Installation and Administration_.
